<p>An asphalt mix comprising a pine extract, the asphalt mix having low viscosity at ambient temperatures, and workable at ambient temperatures. The asphalt mix comprises asphalt cement, biodiesel, pine extract and an anti-stppping agent. The asphalt mix comprises only solvents that are biodegradable. The biodegradable solvents are pine extract and biodiesel. A method of manufacturing an asphalt mix comprising heating aggregate, introducing RAP to the aggregate, dry mixing the RAP and aggregate, forming a coating of AC on all aggregate during the step of dry mixing by extending the length in time of the dry mixing step, separately blending AC, biodegradable solvents, and anti-stnpping agent to produce a blend, and wet mixing the blend into the RAP and aggregate mix.</p> |
